Following 2 types of air cleaning
fi
lters are used in this product.
When you replace them, purchase dedicated air cleaning
fi
lters for this
product.
Apple-catechin
fi
lter: UTR-FA16
(1 sheet)
The Apple-catechin
fi
lter uses static electricity to clean
fi
ne particles and
dust in the air such as tobacco smoke and plant pollen that are too small
to see.
●
This
fi
lter is disposable. Do not wash or reuse it.
●
Once you open the package, use it as soon as possible. The cleaning
effect is reduced if the
fi
lter is left with the package opened.
●
Replace the
fi
lter once every 3 months under normal use.
●
By setting the fan speed high, the air cleaning effect increases.
Ion deodorization
fi
lter: UTR-FA16-2
(Light blue, 1 sheet)
The
fi
lter deodorizes by powerfully decomposing absorbed odors using
the oxidizing and reducing effects of ions generated by the ultra-
fi
ne-
particle ceramic.
●
To maintain the deodorizing effect, clean the
fi
lter once every 3 months
as follows:
1) Remove the
fi
lter.
2)
Flush the
fi
lter with high-pressure hot water until the surface of the
fi
lter is covered with water.
3)
Wash the
fi
lter gently with diluent neutral detergent. Do not wash
it by wringing or rubbing to prevent reducing the deodorizing effect
by damage.
4) Rinse the
fi
lter well with water
fl
ow.
5) Dry the
fi
lter thoroughly in a shaded place.
6) Reinstall the
fi
lter to the indoor unit.
●
Replace the
fi
lter once every 3 years under normal use.
When not using for an extended period
Leave the breaker on for at least 12 hours before starting operation when
it is to be used again.
After extended non-use of the unit
If you have shut down the indoor unit for 1 month or more, perform the
FAN operation for half a day to dry the internal parts thoroughly before
you perform normal operation.
Additional inspection
After long period of use, accumulated dust inside the indoor unit may re-
duce the product performance even if you have maintained the unit with
instructed daily care or cleaning procedures written in this manual.
In such a case, a product inspection is recommended.
For more information, consult authorized service personnel.
TROUBLESHOOTING
The following conditions are not breakdowns or op-
eration failures.
Doesn’t operate immediately:
●
If the unit is stopped and then immediately started again, the com-
pressor will not operate for about 3 minutes, in order to prevent fuse
blowouts.
●
Whenever the electrical breaker is turned off then on again, the protec-
tion circuit will operate for about 3 minutes, preventing unit operation
during that period.
Air
fl
ow is weak or stops:
●
When Heating operation is started, indoor unit’s fan may temporarily
stop, to allow internal parts to warm up.
●
During Heating operation, if the room temperature rises above the
thermostat setting, the outdoor unit will stop, and the indoor unit’s fan
will stop. If you wish to warm the room further, set the thermostat for a
higher setting.
●
During oil recovery operation, the air
fl
ow may stop for approximately
10 minutes. (See page 3)
●
During Heating operation, the unit will temporarily stop operation (be-
tween 4 and 15 minutes) as the Automatic Defrosting mode operates.
(See page 3)
●
The fan may operate at low speed during Dry operation or when the
unit is monitoring the room’s temperature.
●
In the monitor AUTO operation, the fan will operate at low speed.
Flashing lamps:
●
The OPERATION indicator lamp (green)
fl
ashes:
An oil recovery operation is being performed. (See page 3)
●
The OPERATION indicator lamp (green)
fl
ashes:
An automatic defrosting operation is being performed. (See page 3)
●
The OPERATION indicator lamp (green) and TIMER indicator lamp
(orange) are
fl
ashing alternately:
It has recovered from a power outage.
●
The OPERATION indicator lamp (green) and TIMER indicator lamp
(orange) are
fl
ashing simultaneously:
It is operating in trial operation mode. Ask a manager as there may be
maintenance being conducted.
●
The OPERATION indicator lamp (green) lights up and the TIMER
indicator lamp (orange)
fl
ashes:
This is the standby state. (See page 3)
Noise is heard:
●
In the following conditions there are sounds of water
fl
owing from the
indoor unit and the operation sound becomes loud. These are the
sounds of the
fl
owing of refrigerant.
When operation starts
When oil recovery operation
fi
nishes
When automatic defrosting operation
fi
nishes
●
During operation, a slight squeaking sound may be heard. This is the
result of minute expansion and contraction of the panel due to tem-
perature changes.
●
During Heating operation, a sizzling sound may be heard occasionally.
This sound is produced by the Automatic Defrosting operation. (See
page 3)
Smells:
●
Some smell may be emitted from the indoor unit. This smell is the
result of room smells (furniture, tobacco, etc.) which have been taken
into the air conditioner.
Fog comes out of the indoor unit:
●
During Cooling operation, a thin mist may be seen emitted from the
indoor unit. This results from the sudden Cooling of room air by the air
emitted from the air conditioner, resulting in condensation and misting.
Steam comes out of the indoor unit:
●
During Heating operation, the outdoor unit’s fan may stop, and steam
may be seen rising from the unit. This is due to the Automatic Defrost-
ing operation. (See page 3)
Water is produced from the outdoor unit:
●
During Heating operation, water may be produced from the outdoor
unit due to the Automatic Defrosting operation.
